Make external connections according to the following instruction. Check connections after
wiring to make sure all connections are correct. (Do not use the control circuit buzzer to check
connections)
(A) Main circuit’s wiring must separate from other high voltage or high current power line to
avoid noise interference. Refer to the figures below:
A noise filter in the output of the main circuit can suppress conductive noise. To prevent radiative noise,
the wires should be put in a metal pipe and distance from signal lines of other control machines for more
than 30 cm.
The inverter uses dedicated power line A general noise filter may not provide
rightful results
Add a noise filter or separation transformer whenter
shares the power line with other machines.
